OIL-FILTER.

Application filed April 3, 1915.

To all whom it may concern:

Be it known that 1, JOHN H. PAGKER, a citizen of the United States, residing at Pocatello, in the county of Bannock and State of Idaho, have invented a new and useful Oil-Filter, of which the following is a specification.

The present invention appertains to oil filters, and aims to provide an oil filter having novel means for catching the sediment when the oil enters and flows through the casing of the filter, and also having novel means for straining the oil.

It is also within the scope of the invention to provide an oil filter improved generally in its construction, and which is comparatively simple and inexpensive in construction, as well as being practical and eflicient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a vertical section of the filter. taken approximately on the line 11 of Fig. 2. Fig. 2 is a horizontal. section of the device taken on the line 22 of Fig. 1.

In carrying out the invention, there is suitable size. Secured to and projecting upwardly from the bottom of the casing 1 is an annular sleeve 2 which projects to a point between the upper and lower ends of the casing, and which is arranged adjacent but spaced from the periphery or walls of the casing. A depending annular sleeve 3 is arranged within the sleeve 2 and its lower end terminates adjacent but spaced from the bottom or lower end of the casing, while the upper end of the sleeve or apron 3 is flared or turned outward, as at 1, and secured to the periphery or walls of the casing immediately above the upper end oredge of the sleeve 2. The casing and sleeves are concentric, and the sleeves 2 and 3 are arranged close adjacent one another but are spaced apart. The upper end of the sleeve or apron 3 being secured to the casing sus- Specification of Letters Patent.

pends the sleeve 3 within the sleeve 2. An annular chamber 5 is provided between the sleeve 2 and easing 1, and an annular chamher 6 is provided between the two sleeves, while a central chamber 7 is provided within the inner sleeve or apron A downwardly projecting oil inlet pipe 8 is disposed adjacent one side of the casing and has its lower end engaged through the casing adjacent the bottom thereof to communicate with the lower portion of the chamber 5, and the upper end of the inlet or filling pipe 8 is provided with a funnel 9 above the top or upper end of the casing, whereby the waste oil or other oil to be filtered may be readily poured into the pipe 8 to enter the lower portion of the casing.

The bottom of'the casing is provided with a drain cook 10 whereby the sediment may be drained from the chambers (3 and 7, and the casing 1 is provided with one or more drain cocks 11 V communicating with the lower portion of the chamber 5 for draining the said chamber.

A filtering means 12 is disposed within the casing 1 above the sleeves 2 and 3, and comprises upper and lower circular apertured plates 13 and 14- fitting snugly within the casing 1, and having superposed sheets of suitable fabric or filtering material 15 disposedtherebetween. A central clamping bolt 16 is engaged through the plates 13 and 14: and filtering material 15 and bears an upper thumb or wing nut 17 seating upon the plate 15 whereby the plates 13 and 14 may be readily moved toward one another for compressing the filtering material 15 when desired. A nut 18 is threaded upon the bolt 16 and seats against the lower surface of the lower plate 1 1-.

As a means for supporting the straining or filtering means or device 12 within the casing 1, a diametrical bar 19 is terminally secured to the opposite sides of the casing immediately above the sleeve 3, and is provided at its central point with a slot 20. The lower end of the bolt 16 is provided with an elongated head 21 which may be moved downwardly through the slot 20 when the straining or filtering .device is inserted into the casing and when the bolt 16 is rotated to the proper position, and the bolt 16 may then be turned for locking the head 21 thereof under the bar 19 for holding the parts in place.

A chamber 22 is provided between the filtering device 12 and the top or upper end removable cap 23 which when removed permits access to be had to the nut 17 whereby the said nut maybe tightened or loosened for either compressing or loosening the filtering material 15. The casing 1 is also provided with a faucet or other means 2 1 for drawing off the filtered oil from the chamber '22, and is further provided with a faucet or means for drawing off the air from the upper portions of the chambers 5 and 6 which are in communication. The casing is provided with a glass gage 26 between the filtering device 12 and the upper end of the sleeve 3, and with a second glass gage 27 communicating with the chamber 22.

" chamber 5 therefore provides a primary 'level within the chambers 5 and 6.

In operation, the casing is filled with water to a point slightly below the lower plate 1% of the filtering device,-the level :of'

The air 'may be let outof the chambers 5 and 6, by'opening' the faucet or valve 25 in order that the water will rise to the desilrpd 1e waste or other oil to be filtered is then de livered into the pipe 8 and will flow into the lower portion of the chamber 5 which will tendto catch the sediment therein.

The filtered oil may be drawn off from the chamber 22 through the faucet or valve 24, the level of the filtered'oil withinthe chamber 22'being indicated by the gage 27 g It is evident that the plates 13 and let of the filtering device may be drawn together for compressing the filtering material 15, whereby the oil will be filtered most effectively and the compressed filtering material 15 in en'gagingthe casing 1 will prevent the oil from escaping aroundthe filtering device.

without passing through the filtering material.

It is preferable to provide the lower end of the sleeve 3 with feet 1 resting upon or secured to the bottom of the casing, for assisting in supporting the sleeve 3 properly. It is also desirable to provide an annular apertured pipe 9 within the lower portion of the annular chamber 5 to which the lower end of the filling pipe 8 is connected, whereby the oil will enter the pipe 9 from the pipe 8 and will be discharged upwardly within all portions of the chamber 5.

The present device may be readily cleaned out by drawing off all of the water from the chamber 5 by opening the valve 11, and then attaching a hose to the valve 10 and opening the said valve 10 whereby the water will pass through the chambers 6 and 5 out through the open valve 11 for cleaning out the sediment from the chambers 5, 6 and 7. The operation may be reversed, for purpose of cleaning out the sediment, by attaching the hose to the valve 11 and opening the valve 10 whereby the sediment will be carried out through the valve 10 with the water. In cleaning out the device, care should be exercised in drawing off as much oil as possible, so as not to waste the oil. The oil can be forced up through the filtering material by forcing water into the chamber 7 so that the water level rises into the filtering material, and the oil will therefore be forced up into the chamber 22 so that it can be readily drawn off before the cleaning operation.

Having thus described the invention, what is claimed is In a filter, an upright casing, an upwardly projecting sleeve therein providing a chamber having a lower inlet, a depending sleeve within the aforesaid sleeve and having its upper end outturned and secured to the walls of the casing, a filtering device within the casing above the sleeve and comprising apertured plates fitting within the casing and filtering material between said plates, and clamping means engaged through said plates, the casing having an outlet above the filtering device.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
